[Doc Faustus]

I don't think horror is about realism. CGI imposes realism on a genre that's naturally expressionistic and sort of weird. Savini and Screaming Mad George gore is great because it's unreal, but it gives the impression of gore. And the impression is all you need. You know you're watching a movie, you know you're in an unrealistic world, so let it be what it is. If anything, excessive realism gets in the way and damages the otherworldly vibe.
